I used a couple of these on an old case that didn't have fan filters. I covered the 120mm fan mount on the bottom of the case that I use for extraction and also used a filter on the front behind the plastic grille where I cut off part of the steel frame because it was restricting airflow. I've used these filters before and they're easy to clean, either with compressed air (remove filter and spray against the direction the air would normally go through the grate) or, even better, with a vacuum with a brush attachment. This is probably not for demo builds unless you like the more industrial look. But for hidden locations that require a 120mm fan filter, they will outlive/outperform just about anything. I want them to come in black.
